SUMMARY: A low molecular weight type of atypical bovine spongiform encephalopathy (L-BSE) was transmitted to two cynomolgus macaques by intracerebral inoculation of a brain homogenate of cattle with atypical BSE detected in Japan. They developed neurological signs and symptoms at 19 or 20 months post-inoculation and were euthanized 6 months after the onset of total paralysis. Both the incubation period and duration of the disease were shorter than those for experimental transmission of classical BSE (C-BSE) into macaques. Although the clinical manifestations, such as tremor, myoclonic jerking, and paralysis, were similar to those induced upon C-BSE transmission, no premonitory symptoms, such as hyperekplexia and depression, were evident. Most of the abnormal prion protein (PrPSc) was confined to the tissues of the central nervous system, as determined by immunohistochemistry and Western blotting. The PrPSc glycoform that accumulated in the monkey brain showed a similar profile to that of L-BSE and consistent with that in the cattle brain used as the inoculant. PrPSc staining in the cerebral cortex showed a diffuse synaptic pattern by immunohistochemistry, whereas it accumulated as fine and coarse granules and/or small plaques in the cerebellar cortex and brain stem. Severe spongiosis spread widely in the cerebral cortex, whereas florid plaques, a hallmark of variant Creutzfeldt-Jakob disease in humans, were observed in macaques inoculated with C-BSE but not in those inoculated with L-BSE.

To date, 27 cases of L-BSE and 24 cases of H-BSE have been reported worldwide (16), thus meaning that the prevalence of atypical BSE is considerably lower than that of C-BSE. However, recent studies showed that L-BSE is easily transmissible to transgenic mice expressing human (17,18) or bovine (19,20) prion protein, as well as to non-human primates (21), with shorter incubation periods than for the transmission of C-BSE to these animals. The virulent nature of L-BSE has stimulated new concern for human public health since the transmission of C-BSE to humans resulted in variant Creutzfeldt-Jakob disease (vCJD) (4-7), a new emergent prion disease.

Two macaques simultaneously developed neurological signs and symptoms 19-20 months post-inoculation (mpi) with the brain homogenate of BSEI JP24. The monkeys entered the terminal stage of the disease (total paralysis) at 24-25 mpi, Both the onset and duration of the disease were shorter than those reported for the transmission of C-BSE to macaques by us and other groups (27,28). The clinical manifestations such as tremor, myoclonic jerking, and paralysis were similar to those observed during the transmission of C-BSE to ma- caques, whereas the premonitory abnormal behaviors, such as hyperekplexia and depression, seen upon transmission of C-BSE to macaques were not evident (27).
Histopathological analysis and IHC, performed as described previously (29), showed that severe spongiform changes and the accumulation of Prpsc with various patterns were detectable in the brains of both monkeys (Fig. 1). Vacuolization was profound throughout the cerebral cortex, from the frontal to the occipital lobes (Fig. la). Likewise, synaptic-type Prpsc precipitation (30) was observed in the whole cerebral cortex and basal ganglia by IHC (Figs. Ib and c). Dense precipitates and plaques of Prpsc, which had been observed in cattle (JP24) brain (13), were not detected in the cerebrum of the monkeys. Prpsc, in the form of small plaques or coarse granules, was, however, detected in the molecular layer of the cerebellum (Fig. Ie). Despite the severe spongiosis in the cerebral cortex, florid plaques, which are large Prpsc plaques surrounded by vacuoles, a hallmark ofvCJD (4-7,30) and C-BSE transmission to macaques (27,28), were not observed. The histopathology of the brain was therefore similar to that reported for the brain of L-BSE (BASE)-transmitted macaques (21).

A Surprisingly High Number of the Plaque-Like VV sCJD Subtype Among the Polish sCJD—is There a Connection with BASE?
Beata Sikorska and Pawel P. Liberski Department of Molecular Pathology and Neuropathology; Medical University of Lodz; Lodz, Poland
Recently described bovine amyloidotic spongiform encephalopathy (BASE) or L type BSE—was is overrepresented in Poland (15% of all cases of BSE). Moreover, the number of BASE cases in Poland per million bovines is the highest in Europe. A potential human risk from BASE is evident from experimental transmission to “humanized” transgenic animals and primates. Taking into consideration that non-human primate inoculated with BASE had a shorter incubation period than monkeys infected with classical BSE, and that humanized Tg mice have been found to be highly susceptible to infection with atypical form of BSE, it seems probable that BASE may be more pathogenic for humans than BSE, but the transmitted disease may differ from BSE-derived vCJD. Among 47 cases which have been diagnosed as definite in our laboratory, in 19 cases complete histopathological examination and codon 129 status were available. On the basis of the histological pattern and codon 129 status the cases of sCJD were divided into subtypes according to the Parchi&Gambetti classification. The results are as follows: type 1 (MMorMV)- 42%, type 2 (VV)-32%, type 3 (MV)-10.5%, type 4c (MM)- 10.5% and type 5 (VV)-5 %. Although the number of cases is too low to conclude a significantly different distribution of sCJD subtypes in Polish population those data show surprisingly high number of the plaque-like VV sCJD subtype. Interestingly, it was shown before that Tg mice inoculated with BASE showed granular and plaque-like aggregates or PrPSc in brains resembling those observed in VV2 subtype of sCJD.

Key words: L-type BSE, cBSE, cynomolgus macaques, transmission
BSE prion derived from classical BSE (cBSE) or L-type BSE was characterized by inoculation into the brain of cynomolgus macaques. The neurologic manifestation was developed in all cynomolgus macaques at 27–43 months after intracerebral inoculation of brain homogenate from cBSE-affected cattle (BSE JP/6). Second transmission of cBSE from macaque to macaque shortened incubation period to 13–18 months. cBSE-affected macaques showed the similar clinical signs including hyperekplexia, tremor and paralysis in both primary and second transmission.
Two macaques were intracerebrally inoculated brain homogenate from the L-type BSE-affected cattle (BSE JP/24). The incubation periods were 19–20 months in primary transmission.
The clinical course of the L-type BSE-affected macaques differed from that in cBSE-affected macaques in the points of severe myoclonus without hyperekplexia. The glycoform profile of PrPSc detected in macaque CNS was consistent with original pattern of either cBSE or L-typeBSE PrPSc, respectively. Although severe spongiform change in the brain was remarkable in all BSE-affected macaques, severe spongiform spread widely in cerebral cortex in L-type BSE-affected macaques. Heavy accumulation of PrPSc surrounded by vacuola formed florid plaques in cerebral cortex of cBSE-affected macaques. Deposit of PrPSc in L-type BSE-affected macaque was weak and diffuse synaptic pattern in cerebrum, but large PrPSc plaques were evident at cerebellum. MRI analysis, T2, T1, DW and flair sequences, at the time of autopsy revealed that brain atrophy and dilatation of cerebral ventricles were significantly severe in L-type BSE-affected macaques. These results suggest that L-type BSE is more virulent strain to primates comparing to cBSE.

Evidence from Molecular Strain Typing

Key words: molecular analysis, strain typing, atypical BSE, CJD
In 2001, active surveillance for bovine spongiform encephalopathy (BSE) led to the discovery of atypical BSE phenotypes in aged cattle distinct from classical BSE (C-type). These atypical BSE cases had been classified as low L-type (BASE) or high H-type BSE based on the molecular mass and the degree of glycosylation of of the pathological prion protein (PrPSc). Transmission studies in TgBov mice showed that H-type BSE, C-type BSE and BASE behave as distinct prion strains with different incubation periods, PrPSc molecular patterns and pathological phenotypes. A still unclear issue concerns the potential transmissibility and phenotypes of atypical BSEs in humans. We previously indicated that BASE was similar to a distinct subgroup of sporadic form of Creutzfeldt-Jakob disease (sCJD) MV2, based on molecular similarities and on neuropathological pattern of PrP deposition. To investigate a possible link between BASE and sCJD, Kong et al. and Comoy et al. experimentally inoculated TgHu mice (129MM) and a non-human primate respectively, showing in both models that BASE was more virulent compare to BSE. Further, non-human primate reproduced a clinical phenotype resembling to that of sCJD subtype MM2. Here, we presented a comparative analysis of the biochemical fingerprints of PrPSc between the different sCJD subtypes and animal TSEs and after experimental transmission to animals.

Abstract Top Background Human variant Creutzfeldt-Jakob Disease (vCJD) results from foodborne transmission of prions from slaughtered cattle with classical Bovine Spongiform Encephalopathy (cBSE). Atypical forms of BSE, which remain mostly asymptomatic in aging cattle, were recently identified at slaughterhouses throughout Europe and North America, raising a question about human susceptibility to these new prion strains.
Methodology/Principal Findings Brain homogenates from cattle with classical BSE and atypical (BASE) infections were inoculated intracerebrally into cynomolgus monkeys (Macacca fascicularis), a non-human primate model previously demonstrated to be susceptible to the original strain of cBSE. The resulting diseases were compared in terms of clinical signs, histology and biochemistry of the abnormal prion protein (PrPres). The single monkey infected with BASE had a shorter survival, and a different clinical evolution, histopathology, and prion protein (PrPres) pattern than was observed for either classical BSE or vCJD-inoculated animals. Also, the biochemical signature of PrPres in the BASE-inoculated animal was found to have a higher proteinase K sensitivity of the octa-repeat region. We found the same biochemical signature in three of four human patients with sporadic CJD and an MM type 2 PrP genotype who lived in the same country as the infected bovine.
Conclusion/Significance Our results point to a possibly higher degree of pathogenicity of BASE than classical BSE in primates and also raise a question about a possible link to one uncommon subset of cases of apparently sporadic CJD. Thus, despite the waning epidemic of classical BSE, the occurrence of atypical strains should temper the urge to relax measures currently in place to protect public health from accidental contamination by BSE-contaminated products.

Session I - Prions: Structure, Strain and Detection (II)
Searching for BASE Strain Signature in Sporadic Creutzfedlt-Jakob Disease
Gianluigi Zanusso
Department of Neurological and Visual Sciences, Section of Clinical Neurology University of Verona, Verona, Italy.
Bovine amyloidotic spongiform encephalopathy (BASE) is a newly recognized form of bovine prion disease, which was originally detected in Italy in 2004 as an effect of active surveillance. BASE or BSE L-type (L is referred to the lower electrophoretic PrPSc migration than classical BSE) has now been reported in several countries, including Japan. All field cases of BASE were older than 8 years and neurologically normal at the time of slaughtered. By experimental transmission, we defined the disease phenotype of cattle BASE, which is quite distinct from that seen in typical BSE and characterized by mental dullness and amyotrophy. Surprisingly, following intraspecies and interspecies transmission the incubation period of BASE was shorter than BSE. The relatively easy transmission of BASE isolate as well as the molecular similarity with sporadic Creutzfeldt-Jakob disease (sCJD) have raised concern regarding its potential passage to humans. Tg humanized mice Met/Met at codon 129 challenged with both BSE and BASE isolates, showed a resistance to BSE but a susceptibility to BASE at a 60% rate; in addition, BASE-inoculated Cynomolgus (129 Met/Met) had shorter incubation periods than BSE-inoculated primates. In this study we compared the biochemical properties of PrPSc in Cynomolgus and in TgHu Met/Met mice challenged with BSE and BASE strains, by conventional SDS-PAGE analysis and 2D separation. The results obtained disclose distinct conformational changes in PrPSc, which are dependent on the inoculated host but not on the codon 129 genotype.

Molecular Features of the Protease-resistant Prion Protein (PrPres) in H-type BSE

Western blot analyses of PrPres accumulating in the brain of BSE-infected cattle have demonstrated 3 different molecular phenotypes regarding to the apparent molecular masses and glycoform ratios of PrPres bands. We initially described isolates (H-type BSE) essentially characterized by higher PrPres molecular mass and decreased levels of the diglycosylated PrPres band, in contrast to the classical type of BSE. This type is also distinct from another BSE phenotype named L-type BSE, or also BASE (for Bovine Amyloid Spongiform Encephalopathy), mainly characterized by a low representation of the diglycosylated PrPres band as well as a lower PrPres molecular mass. Retrospective molecular studies in France of all available BSE cases older than 8 years old and of part of the other cases identified since the beginning of the exhaustive surveillance of the disease in 20001 allowed to identify 7 H-type BSE cases, among 594 BSE cases that could be classified as classical, L- or H-type BSE. By Western blot analysis of H-type PrPres, we described a remarkable specific feature with antibodies raised against the C-terminal region of PrP that demonstrated the existence of a more C-terminal cleaved form of PrPres (named PrPres#2 ), in addition to the usual PrPres form (PrPres #1). In the unglycosylated form, PrPres #2 migrates at about 14 kDa, compared to 20 kDa for PrPres #1. The proportion of the PrPres#2 in cattle seems to by higher compared to the PrPres#1. Furthermore another PK-resistant fragment at about 7 kDa was detected by some more N-terminal antibodies and presumed to be the result of cleavages of both N- and C-terminal parts of PrP. These singular features were maintained after transmission of the disease to C57Bl/6 mice. The identification of these two additional PrPres fragments (PrPres #2 and 7kDa band) reminds features reported respectively in sporadic Creutzfeldt-Jakob disease and in Gerstmann-Sträussler-Scheinker (GSS) syndrome in humans.

Abstract
To characterize the biological and biochemical properties of H-type bovine spongiform encephalopathy (BSE), a transmission study with a Canadian H-type isolate was performed with bovinized transgenic mice (TgBoPrP), which were inoculated intracerebrally with brain homogenate from cattle with H-type BSE. All mice exhibited characteristic neurologic signs, and the subsequent passage showed a shortened incubation period. The distribution of disease-associated prion protein (PrPSc) was determined by immunohistochemistry, Western blot, and paraffin-embedded tissue (PET) blot. Biochemical properties and higher molecular weight of the glycoform pattern were well conserved within mice. Immunolabeled granular PrPSc, aggregates, and/or plaque-like deposits were mainly detected in the following brain locations: septal nuclei, subcallosal regions, hypothalamus, paraventricular nucleus of the thalamus, interstitial nucleus of the stria terminalis, and the reticular formation of the midbrain. Weak reactivity was detected by immunohistochemistry and PET blot in the cerebral cortex, most thalamic nuclei, the hippocampus, medulla oblongata, and cerebellum. These findings indicate that the H-type BSE prion has biological and biochemical properties distinct from those of C-type and L-type BSE in TgBoPrP mice, which suggests that TgBoPrP mice constitute a useful animal model to distinguish isolates from BSE-infected cattle.

let's take a closer look at this new prionpathy or prionopathy, and then let's look at the g-h-BSEalabama mad cow.
This new prionopathy in humans? the genetic makeup is IDENTICAL to the g-h-BSEalabama mad cow, the only _documented_ mad cow in the world to date like this, ......wait, it get's better. this new prionpathy is killing young and old humans, with LONG DURATION from onset of symptoms to death, and the symptoms are very similar to nvCJD victims, OH, and the plaques are very similar in some cases too, bbbut, it's not related to the g-h-BSEalabama cow, WAIT NOW, it gets even better, the new human prionpathy that they claim is a genetic TSE, has no relation to any gene mutation in that family. daaa, ya think it could be related to that mad cow with the same genetic make-up ??? there were literally tons and tons of banned mad cow protein in Alabama in commerce, and none of it transmitted to cows, and the cows to humans there from ??? r i g h t $$$
ALABAMA MAD COW g-h-BSEalabama
In this study, we identified a novel mutation in the bovine prion protein gene (Prnp), called E211K, of a confirmed BSE positive cow from Alabama, United States of America. This mutation is identical to the E200K pathogenic mutation found in humans with a genetic form of CJD. This finding represents the first report of a confirmed case of BSE with a potential pathogenic mutation within the bovine Prnp gene. We hypothesize that the bovine Prnp E211K mutation most likely has caused BSE in "the approximately 10-year-old cow" carrying the E221K mutation.

Seven main threats for the future linked to prions
The NeuroPrion network has identified seven main threats for the future linked to prions.
First threat
The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed. Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.
Second threat

Atypical BSE in Cattle
To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE. In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.
This study will contribute to a correct definition of specified risk material (SRM) in atypical BSE. The incumbent of this position will develop new and transfer existing, ultra-sensitive methods for the detection of atypical BSE in tissue of experimentally infected cattle.

Bovine spongiform encephalopathy (BSE), the prion disease in cattle, was widely believed to be caused by only one strain, BSE-C. BSE-C causes the fatal prion disease named new variant Creutzfeldt-Jacob disease in humans. Two atypical BSE strains, bovine amyloidotic spongiform encephalopathy (BASE, also named BSE-L) and BSE-H, have been discovered in several countries since 2004; their transmissibility and phenotypes in humans are unknown. We investigated the infectivity and human phenotype of BASE strains by inoculating transgenic (Tg) mice expressing the human prion protein with brain homogenates from two BASE strain-infected cattle. Sixty percent of the inoculated Tg mice became infected after 20 to 22 months of incubation, a transmission rate higher than those reported for BSE-C. A quarter of BASE strain-infected Tg mice, but none of the Tg mice infected with prions causing a sporadic human prion disease, showed the presence of pathogenic prion protein isoforms in the spleen, indicating that the BASE prion is intrinsically lymphotropic. The pathological prion protein isoforms in BASE strain-infected humanized Tg mouse brains are different from those from the original cattle BASE or sporadic human prion disease. Minimal brain spongiosis and long incubation times are observed for the BASE strain-infected Tg mice. These results suggest that in humans, the BASE strain is a more virulent BSE strain and likely lymphotropic.

Classical BSE is a world-wide prion disease in cattle, and the classical BSE strain (BSE-C) has led to over 200 cases of clinical human infection (variant CJD). Two atypical BSE strains, BSE-L (also named BASE) and BSE-H, have been discovered in three continents since 2004. The first case of naturally occurring BSE with mutated bovine PrP gene (termed BSE-M) was also found in 2006 in the USA. The transmissibility and phenotypes of these atypical BSE strains/isolates in humans were unknown. We have inoculated humanized transgenic mice with classical and atypical BSE strains (BSE-C, BSE-L, BSE-H) and the BSE-M isolate. We have found that the atypical BSE-L strain is much more virulent than the classical BSE-C. The atypical BSE-H strain is also transmissible in the humanized transgenic mice with distinct phenotype, but no transmission has been observed for the BSE-M isolate so far.

Rare BSE mutation raises concerns over risks to public health
SIR — Atypical forms (known as H- and L-type) of bovine spongiform encephalopathy (BSE) have recently appeared in several European countries as well as in Japan, Canada and the United States. This raises the unwelcome possibility that variant Creutzfeldt–Jakob disease (vCJD) could increase in the human population. Of the atypical BSE cases tested so far, a mutation in the prion protein gene (PRNP) has been detected in just one, a cow in Alabama with BSE; her healthy calf also carried the mutation (J. A. Richt and S. M. Hall PLoS Pathog. 4, e1000156; 2008). This raises the possibility that the disease could occasionally be genetic in origin. Indeed, the report of the UK BSE Inquiry in 2000 suggested that the UK epidemic had most likely originated from such a mutation and argued against the scrapierelated assumption. Such rare potential pathogenic PRNP mutations could occur in countries at present considered to be free of BSE, such as Australia and New Zealand. So it is important to maintain strict surveillance for BSE in cattle, with rigorous enforcement of the ruminant feed ban (many countries still feed ruminant proteins to pigs). Removal of specified risk material, such as brain and spinal cord, from cattle at slaughter prevents infected material from entering the human food chain. Routine genetic screening of cattle for PRNP mutations, which is now available, could provide additional data on the risk to the public. Because the point mutation identified in the Alabama animals is identical to that responsible for the commonest type of familial (genetic) CJD in humans, it is possible that the resulting infective prion protein might cross the bovine–human species barrier more easily. Patients with vCJD continue to be identified. The fact that this is happening less often should not lead to relaxation of the controls necessary to prevent future outbreaks. Malcolm A.

Our findings demonstrate that cervid PrPSc, upon strain adaptation by serial passages in vitro or in cervid transgenic mice, is capable of converting human PrPC to produce PrPSc with unique biochemical properties, likely representing a new human prion strain. The newly generated CWD-huPrPSc material has been inoculated into transgenic mice expressing human PrP to study infectivity and disease phenotype and this data will be published elsewhere.

Submitted to: Journal of Comparative Pathology Publication Type: Peer Reviewed Journal Publication Acceptance Date: July 25, 2005 Publication Date: January 1, 2006 Citation: Hamir, A.N., Kunkle, R.A., Miller, J.M., Greenlee, J.J., Richt, J.A. 2006. Experimental second passage of chronic wasting disease (CWD(mule deer)) agent to cattle. Journal of Comparative Pathology. 134(1):63-69.
Interpretive Summary: To compare the findings of experimental first and second passage of chronic wasting disease (CWD) in cattle, 6 calves were inoculated into the brain with CWD-mule deer agent previously (first) passaged in cattle. Two other uninoculated calves served as controls. Beginning 10-12 months post inoculation (PI), all inoculates lost appetite and weight. Five animals subsequently developed clinical signs of central nervous system (CNS) abnormality. By 16.5 months PI, all cattle had been euthanized because of poor prognosis. None of the animals showed microscopic lesions of spongiform encephalopathy (SE) but the CWD agent was detected in their CNS tissues by 2 laboratory techniques (IHC and WB). These findings demonstrate that inoculated cattle amplify CWD agent but also develop clinical CNS signs without manifestation of microscopic lesions of SE. This situation has also been shown to occur following inoculation of cattle with another TSE agent, namely, sheep scrapie. The current study confirms previous work that indicates that the diagnostic tests currently used for confirmation of bovine spongiform encephalopathy (BSE) in the U.S. would detect CWD in cattle, should it occur naturally. Furthermore, it raises the possibility of distinguishing CWD from BSE in cattle due to the absence of microscopic lesions and a unique multifocal distribution of PrPres, as demonstrated by IHC, which in this study, appears to be more sensitive than the WB. Technical Abstract: To compare clinicopathological findings of first and second passage of chronic wasting disease (CWD) in cattle, a group of calves (n=6) were intracerebrally inoculated with CWD-mule deer agent previously (first) passaged in cattle. Two other uninoculated calves served as controls. Beginning 10-12 months post inoculation (PI), all inoculates lost appetite and lost weight. Five animals subsequently developed clinical signs of central nervous system (CNS) abnormality. By 16.5 months PI, all cattle had been euthanized because of poor prognosis. None of the animals showed microscopic lesions of spongiform encephalopathy (SE) but PrPres was detected in their CNS tissues by immunohistochemistry (IHC) and Western blot (WB) techniques. These findings demonstrate that intracerebrally inoculated cattle not only amplify CWD PrPres but also develop clinical CNS signs without manifestation of morphologic lesions of SE. This situation has also been shown to occur following inoculation of cattle with another TSE agent, scrapie. The current study confirms previous work that indicates the diagnostic techniques currently used for confirmation of bovine spongiform encephalopathy (BSE) in the U.S. would detect CWD in cattle, should it occur naturally. Furthermore, it raises the possibility of distinguishing CWD from BSE in cattle due to the absence of neuropathologic lesions and a unique multifocal distribution of PrPres, as demonstrated by IHC, which in this study, appears to be more sensitive than the WB.

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America
update October 2009
T. Singeltary
Bacliff, TX, USA
Background:
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.
Methods:
12 years independent research of available data
Results:
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.
Conclusion:
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

Declaration of Prion as a Pest Under FIFRA and Amendment of EPA's Regulatory Definition of Pests To Include Prion EPA-HQ-OPP-2010-0427
EPA-HQ-OPP-2010-0427
[Federal Register: January 26, 2011 (Volume 76, Number 17)] [Proposed Rules] [Page 4602-4608] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr26ja11-30]

Declaration of Prion as a Pest Under FIFRA and Amendment of EPA's Regulatory Definition of Pests To Include Prion
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA proposes to declare a prion (i.e., proteinaceous infectious particle) a ``pest'' under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and to amend its regulations to expressly include prion within the regulatory definition of pest. EPA currently considers a prion to be a pest under FIFRA, so a product intended to reduce the infectivity of any prion on inanimate surfaces (i.e., a ``prion-related product'') is considered to be a pesticide and regulated as such. Any company seeking to distribute or sell a pesticide product regulated under FIFRA must obtain a section 3 registration, section 24(c) registration, or a section 18 emergency exemption before it can be distributed or sold in the United States. This proposed rule would codify the Agency's current interpretation of FIFRA, and provides interested parties the opportunity to comment about how it is adding prion to the list of pests in the regulatory definition of pest. This amendment, together with the formal declaration that a prion is a pest, will eliminate any confusion about the status of prion-related products under FIFRA. Codifying the Agency's current interpretation of FIFRA will not change the manner in which EPA currently regulates prion-related products under FIFRA sections 3, 24(c) and 18. Regulating prion-related products under FIFRA is appropriate for protecting human health and the environment against unreasonable adverse effects and ensuring that such products are effective.

II. Background
A. What action is the Agency taking?
EPA has decided that under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) a prion is considered to be a pest, and proposes to declare a prion to be a pest and to explicitly include it in the lists of pests in 40 CFR 152.5. These actions would affirm the Agency's authority to regulate products distributed or sold for the purpose of reducing the infectivity of prions on inanimate surfaces (i.e., prion-related products). Prion-related products are currently regulated under FIFRA and subject to all requirements and provisions of the Act based on EPA's September 10, 2003 decision that prions share enough characteristics of an ``other micro-organism'' or ``form of life'' (as those terms are used in FIFRA) to fall within the scope of FIFRA section 2(t) and 40 CFR 152.5(d). This proposal ensures that the regulatory definition reflects the Agency's authority to regulate products distributed or sold for the purpose of reducing the infectivity of prions on inanimate surfaces (i.e., prion-related products). The primary impact of declaring that a prion is a pest and including ``prion'' in the regulatory definition of ``pest'' is to provide regulatory clarity that prion-related products must be registered or exempted under FIFRA sections 3, 24(c), or 18 before such products may be distributed or sold in the United States. Note that not all prions and prion-related products are affected by the proposed rule. Firstly, EPA's regulations at 40 CFR 152.5(d) exclude pests ``* * * in or on living man or other living animals and those on or in processed food or processed animal feed, beverages, drugs * * * and cosmetics.'' Therefore, the proposed rule would not apply to those uses of prion-related products. Secondly, the definition of ``pesticide'' in FIFRA section 2(u) excludes new animal drugs and liquid chemical sterilants intended for use on a critical or semi- critical device. Accordingly, products which fall into those categories would not be covered by the proposed rule.

To assure that it considers key available scientific studies that are relevant to the issue of whether a prion is a “pest” under FIFRA, the Work Group drafted a review paper. While the paper received intra-Agency review, it was not subjected to peer review outside of EPA. Accordingly, EPA seeks the SAP’s peer review of the attached, draft review paper (USEPA 2008). Some of the key references cited in the review paper have been provided to the SAP.EPA wishes to point out that the NPRM will also focus on legal and policy matters that are not addressed in depth in the “white paper.” EPA is presenting this paper to the SAP solely for review as to its characterization of the scientific issues, and is not asking the SAP to interpret legal/policy issues such as Congress’ intent in drafting FIFRA.•Please comment on the accuracy of the characterization of the nature of prions, and the adequacy of the review of the relevant scie ific information to support that characterization, as presented in EPA’s draft paper, “Scientific Information Concerning the Issue of Whether Prions Are a ‘Pest’ under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).”5:00 P.M.

Follow-up from Previous Day’s Discussion – Jeff Kempter, Senior Advisor, Antimicrobial Division, Office of Pesticide Programs, EPA9:15 A.M. Charge to Panel – Question 22. Efficacy Guidance Test Method Issue: Whether the specific test systems recommended in the draft guidance document are scientifically appropriate to support the registration of pesticide products with prion-related claims.The draft efficacy guidance document (USEPA 2009) recommends a carrier-based, animal infectivity test method, if the intended use of a product is for treating environmental surfaces, and a suspension-based, animal infectivity test method if the intended use of a product is for treating liquids. The draft efficacy guidance document also states that the test methods may either be end-point titration or incubation time interval assays. EPA is interested in knowing the SAP’s opinion on whether these recommended test systems are scientifically sound and appropriate approaches to evaluating the efficacy of pesticide products with prion-related claims. EPA would also like to know whether the SAP recommends that other test methods be considered to evaluate the efficacy of pesticide products used either on•b.3.

Lunch1:00 P.M. Charge to Panel – Question 44. Efficacy Guidance Labeling Claim Issue: Whether the labeling claim described in the draft guidance document is scientifically appropriate based on the recommended test systems and product performance standard.The draft efficacy guidance document recommends a carefully worded labeling claim statement: “Has been demonstrated to reduce infeci ity of prions (TSE agents) based on testing using (insert type of organism in which the prions were raised) (insert prion type).” EPA believes that claims that may normally be applied to microorganisms (e.g., “destroy,” “mitigate,” “eliminate,” “control”) may be misleading when applied to prions. Because currently available test methods can only measure a reduction in infectivity, and the total elimination or destruction of prions cannot be•5. Efficacy Guidance Hierarchy Issue: Whether different prion types exhibit variation in the degree of resistance to inactivation by pesticide chemicals and whether a hierarchy of resistance by prion type can be reliably determined at this time.Comparisons of different types of prions in a common animal infectivity assay indicate there may be significant differences with regard to their ability to resist inactivation by pesticide chemicals. For example, Peretz et al. (2006) compared the resistance of hamster scrapie and human CJD prions in transgenic mice expressing either hamster PrP or a chimeric mouse-human PrP transgene and found that human sCJD prion tested was 100,000 fold more difficult to inactivate than hamster Sc237 prion. Preliminary additional studies indicate that the cow BSE prion may be even more resistant to inactivation than the human CJD prion (Giles et al. 2006; 2008 in press).measured, EPA believes that “reduce infectivity” is the only appropriate claim.Please comment on the scientific appropriateness of the term “reduce infectivity” in a label claim to reflect the action of a pesticide on prions.3:00 P.M.

Interference at the EPA
Science and Politics at the U.S. Environmental Protection Agency
The U.S. Environmental Protection Agency (EPA) has the simple yet profound charge "to protect human health and the environment." EPA scientists apply their expertise to protect the public from air and water pollution, clean up hazardous waste, and study emerging threats such as global warming. Because each year brings new and potentially toxic chemicals into our homes and workplaces, because air pollution still threatens our public health, and because environmental challenges are becoming more complex and global, a strong and capable EPA is more important than ever.
Yet challenges from industry lobbyists and some political leaders to the agency's decisions have too often led to the suppression and distortion of the scientific findings underlying those decisions—to the detriment of both science and the health of our nation. While every regulatory agency must balance scientific findings with other considerations, policy makers need access to the highest-quality scientific information to make fully informed decisions.
Concern over this problem led the Union of Concerned Scientists (UCS) to investigate political interference in science at the EPA. The investigation combines dozens of interviews with current and former EPA staff, analysis of government documents, more than 1,600 responses to a survey sent to current EPA scientists, and written comments from EPA scientists.
The results of these investigations show an agency under siege from political pressures. On numerous issues—ranging from mercury pollution to groundwater contamination to climate change—political appointees have edited scientific documents, manipulated scientific assessments, and generally sought to undermine the science behind dozens of EPA regulations.
These findings highlight the need for strong reforms to protect EPA scientists, make agency decision making more transparent, and reduce politicization of the regulatory process. Congress, the next president, and the next EPA Administrator must restore independence and scientific integrity to the EPA by:
Protecting EPA Scientists: Scientists should be free to report the distortion, manipulation, and suppression of their work without fear of retribution. Congress should pass a whistleblower law that includes protection for scientists. The EPA should adopt a communications policy that lets scientists speak freely to the press about their findings. Making the EPA More Transparent: Too many decisions are made behind closed doors with little accountability. The EPA’s scientific findings should be freely available to the public. The EPA should open up its decision-making process to congressional and public scrutiny to help reveal misuses of science Reforming the Regulatory Process: The White House should not change scientific findings in order to weaken, delay, or prevent new public protections. Ensuring Robust Scientific Input to EPA's Decision Making: The EPA should review and strengthen how it uses the scientific expertise of its staff and external advisory committees to create policies—especially when scientific input is critical or required by law. Depoliticizing Funding, Monitoring, and Enforcement: Problems with funding, monitoring and enforcement also need to be addressed by Congress and the next President to ensure that the EPA is the robust environmental agency that our country needs. Political interference is not unique to the EPA.

Likewise, some agency records of decision, as well as internal memoranda, establish precedent for regulatory policy making that at times extend the regulatory reach of federal agencies far beyond the statutorily mandated powers given by Congress. A recent example of a record of decision with regulatory impact would be the EPA’s decision to regulate prions.4 Prions are protein structures which, when infectious, are suspected of causing transmissible spongiform encephalopathy diseases, such as mad cow disease in cattle.5 EPA’s decision to classify prions as “pests” under FIFRA stems from an internal agency memorandum asserting jurisdiction over prions,6 even though prions are not living things (a prerequisite for EPA jurisdiction under FIFRA).7 Moreover, acting under the authority granted to itself in this memorandum, EPA issued emergency exemptions to several states to authorize the use of pesticides not registered under FIFRA to treat prioninfected surfaces. Therefore, EPA is treating this memorandum as though it is the issuance of a rule, without providing notice to the public or the opportunity to comment on the agency’s interpretation of its authoritative scope.8 The U.S. Chamber specifically requested EPA publish its prior discussion in the Federal Register for notice and comment, but EPA did not respond to that request. 3 Letter from Robert P.

While FSIS recommends the use of disinfectants, EPA regulates disinfectants under FIFRA. Prior to 2003, prions were not considered pests, and therefore their treatment with disinfectants was not regulated. In September of 2003, EPA classified prions as a pest (Hazen, 2004) and, therefore, the agency was required to regulate the “microorganisms” under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

White House invokes executive privilege in EPA inquiry
The Bush administration refuses to turn over subpoenaed documents related to the agency's decision to prevent California from enacting stricter emissions standards than the federal government.
By Richard Simon, Los Angeles Times Staff Writer
June 21, 2008
WASHINGTON -- Escalating a fight with Democrats on Capitol Hill, the White House on Friday invoked executive privilege in refusing to turn over documents to a congressional committee investigating the Environmental Protection Agency's decision to deny California permission to implement its own vehicle emission standards.
The Bush administration asserted executive privilege hours before the House Oversight and Government Reform Committee was to vote on whether to bring contempt-of-Congress proceedings against EPA Administrator Stephen L. Johnson and Susan Dudley, administrator of regulatory affairs in the White House Office of Management and Budget, for refusing to turn over subpoenaed documents.
Committee Chairman Henry A. Waxman (D-Beverly Hills) put off a vote on the contempt resolutions while he considers his options.
"I don't think we've had a situation like this since Richard Nixon was president," he said, appearing determined to press ahead, even if it leads to a court fight. "We don't know whether this privilege that's being asserted is valid or not."
Presidents since George Washington have claimed rights to executive branch confidentiality, according to the nonpartisan Congressional Research Service. The Bush White House invoked executive privilege to prevent officials from testifying about the dismissal of nine U.S. attorneys in 2006. President Clinton cited presidential privilege during investigations into the Monica Lewinsky scandal and on other issues.
House and Senate committees have been investigating what role the White House played in EPA decisions preventing California and other states from enacting tougher emissions rules than the federal government and in the EPA's approval of new ozone pollution standards.
The administration's claim of executive privilege is the latest twist in the escalating legal and political battle over California's efforts to implement its own law combating global warming. Critics of the EPA decision contend that it was based on politics, not science or the law.
As Waxman considered his next move in his fight with the White House, another House committee in the room next door grilled former Bush Press Secretary Scott McClellan, who wrote a revealing book about his days in the White House. The hearings were a sign of determination by Democrats not to ease up on their oversight activities, even in the final months of the Bush administration.
In asserting executive privilege in the EPA inquiry, the administration made public a copy of a letter sent to the president by Atty. Gen. Michael B. Mukasey saying that releasing internal documents "could inhibit the candor of future deliberations among the president's staff."
EPA spokesman Tim Lyons said the agency had provided the committee with more than 7,000 documents and devoted 2,200 hours of staff time to responding to requests for information, and he called it "disappointing" that the committee had decided to "politicize environmental regulations."
Jim Nussle, director of the Office of Management and Budget, took issue with Waxman's "sudden and unwarranted" move to consider contempt proceedings, noting that Dudley had appeared before Waxman's committee last month and was asked "only four questions" -- and only one by the panel chairman.
"There is no valid reason for moving from mutual cooperation to unilateral confrontation," Nussle wrote Waxman.
Waxman said: "I am very disappointed and disturbed that the administration is keeping this information from us, and I think we have a right to it."

Declaration of Prion as a Pest Under FIFRA and Amendment of EPA's Regulatory Definition of Pests To Include Prion
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA proposes to declare a prion (i.e., proteinaceous infectious particle) a ``pest'' under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and to amend its regulations to expressly include prion within the regulatory definition of pest. EPA currently considers a prion to be a pest under FIFRA, so a product intended to reduce the infectivity of any prion on inanimate surfaces (i.e., a ``prion-related product'') is considered to be a pesticide and regulated as such. Any company seeking to distribute or sell a pesticide product regulated under FIFRA must obtain a section 3 registration, section 24(c) registration, or a section 18 emergency exemption before it can be distributed or sold in the United States. This proposed rule would codify the Agency's current interpretation of FIFRA, and provides interested parties the opportunity to comment about how it is adding prion to the list of pests in the regulatory definition of pest. This amendment, together with the formal declaration that a prion is a pest, will eliminate any confusion about the status of prion-related products under FIFRA. Codifying the Agency's current interpretation of FIFRA will not change the manner in which EPA currently regulates prion-related products under FIFRA sections 3, 24(c) and 18. Regulating prion-related products under FIFRA is appropriate for protecting human health and the environment against unreasonable adverse effects and ensuring that such products are effective.

Make sure to submit your comments by the comment period deadline identified.
II. Background
A. What action is the Agency taking?
EPA has decided that under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) a prion is considered to be a pest, and proposes to declare a prion to be a pest and to explicitly include it in the lists of pests in 40 CFR 152.5. These actions would affirm the Agency's authority to regulate products distributed or sold for the purpose of reducing the infectivity of prions on inanimate surfaces (i.e., prion-related products). Prion-related products are currently regulated under FIFRA and subject to all requirements and provisions of the Act based on EPA's September 10, 2003 decision that prions share enough characteristics of an ``other micro-organism'' or ``form of life'' (as those terms are used in FIFRA) to fall within the scope of FIFRA section 2(t) and 40 CFR 152.5(d). This proposal ensures that the regulatory definition reflects the Agency's authority to regulate products distributed or sold for the purpose of reducing the infectivity of prions on inanimate surfaces (i.e., prion-related products). The primary impact of declaring that a prion is a pest and including ``prion'' in the regulatory definition of ``pest'' is to provide regulatory clarity that prion-related products must be registered or exempted under FIFRA sections 3, 24(c), or 18 before such products may be distributed or sold in the United States. Note that not all prions and prion-related products are affected by the proposed rule. Firstly, EPA's regulations at 40 CFR 152.5(d) exclude pests ``* * * in or on living man or other living animals and those on or in processed food or processed animal feed, beverages, drugs * * * and cosmetics.'' Therefore, the proposed rule would not apply to those uses of prion-related products. Secondly, the definition of ``pesticide'' in FIFRA section 2(u) excludes new animal drugs and liquid chemical sterilants intended for use on a critical or semi- critical device. Accordingly, products which fall into those categories would not be covered by the proposed rule.
[[Page 4604]]
B. What is the Agency's authority for taking this action?
This action is issued under the authority of sections 2 through 34 of FIFRA (7 U.S.C. 136-136y).

To assure that it considers key available scientific studies that are relevant to the issue of whether a prion is a “pest” under FIFRA, the Work Group drafted a review paper. While the paper received intra-Agency review, it was not subjected to peer review outside of EPA. Accordingly, EPA seeks the SAP’s peer review of the attached, draft review paper (USEPA 2008). Some of the key references cited in the review paper have been provided to the SAP.EPA wishes to point out that the NPRM will also focus on legal and policy matters that are not addressed in depth in the “white paper.” EPA is presenting this paper to the SAP solely for review as to its characterization of the scientific issues, and is not asking the SAP to interpret legal/policy issues such as Congress’ intent in drafting FIFRA.•Please comment on the accuracy of the characterization of the nature of prions, and the adequacy of the review of the relevant scie ific information to support that characterization, as presented in EPA’s draft paper, “Scientific Information Concerning the Issue of Whether Prions Are a ‘Pest’ under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).”5:00 P.M.

Efficacy Guidance Test Method Issue: Whether the specific test systems recommended in the draft guidance document are scientifically appropriate to support the registration of pesticide products with prion-related claims.The draft efficacy guidance document (USEPA 2009) recommends a carrier-based, animal infectivity test method, if the intended use of a product is for treating environmental surfaces, and a suspension-based, animal infectivity test method if the intended use of a product is for treating liquids. The draft efficacy guidance document also states that the test methods may either be end-point titration or incubation time interval assays. EPA is interested in knowing the SAP’s opinion on whether these recommended test systems are scientifically sound and appropriate approaches to evaluating the efficacy of pesticide products with prion-related claims. EPA would also like to know whether the SAP recommends that other test methods be considered to evaluate the efficacy of pesticide products used either on•b.3.

Because currently available test methods can only measure a reduction in infectivity, and the total elimination or destruction of prions cannot be•5. Efficacy Guidance Hierarchy Issue: Whether different prion types exhibit variation in the degree of resistance to inactivation by pesticide chemicals and whether a hierarchy of resistance by prion type can be reliably determined at this time.Comparisons of different types of prions in a common animal infectivity assay indicate there may be significant differences with regard to their ability to resist inactivation by pesticide chemicals. For example, Peretz et al. (2006) compared the resistance of hamster scrapie and human CJD prions in transgenic mice expressing either hamster PrP or a chimeric mouse-human PrP transgene and found that human sCJD prion tested was 100,000 fold more difficult to inactivate than hamster Sc237 prion. Preliminary additional studies indicate that the cow BSE prion may be even more resistant to inactivation than the human CJD prion (Giles et al. 2006; 2008 in press).measured, EPA believes that “reduce infectivity” is the only appropriate claim.Please comment on the scientific appropriateness of the term “reduce infectivity” in a label claim to reflect the action of a pesticide on prions.3:00 P.M.

Subject: Interference at the EPA Science and Politics at the U.S. Environmental Protection Agency
Reports and Research
Interference at the EPA
Science and Politics at the U.S. Environmental Protection Agency
The U.S. Environmental Protection Agency (EPA) has the simple yet profound charge "to protect human health and the environment." EPA scientists apply their expertise to protect the public from air and water pollution, clean up hazardous waste, and study emerging threats such as global warming. Because each year brings new and potentially toxic chemicals into our homes and workplaces, because air pollution still threatens our public health, and because environmental challenges are becoming more complex and global, a strong and capable EPA is more important than ever.
Yet challenges from industry lobbyists and some political leaders to the agency's decisions have too often led to the suppression and distortion of the scientific findings underlying those decisions—to the detriment of both science and the health of our nation. While every regulatory agency must balance scientific findings with other considerations, policy makers need access to the highest-quality scientific information to make fully informed decisions.
Concern over this problem led the Union of Concerned Scientists (UCS) to investigate political interference in science at the EPA. The investigation combines dozens of interviews with current and former EPA staff, analysis of government documents, more than 1,600 responses to a survey sent to current EPA scientists, and written comments from EPA scientists.
The results of these investigations show an agency under siege from political pressures. On numerous issues—ranging from mercury pollution to groundwater contamination to climate change—political appointees have edited scientific documents, manipulated scientific assessments, and generally sought to undermine the science behind dozens of EPA regulations.
These findings highlight the need for strong reforms to protect EPA scientists, make agency decision making more transparent, and reduce politicization of the regulatory process. Congress, the next president, and the next EPA Administrator must restore independence and scientific integrity to the EPA by:
Protecting EPA Scientists: Scientists should be free to report the distortion, manipulation, and suppression of their work without fear of retribution. Congress should pass a whistleblower law that includes protection for scientists. The EPA should adopt a communications policy that lets scientists speak freely to the press about their findings. Making the EPA More Transparent: Too many decisions are made behind closed doors with little accountability. The EPA’s scientific findings should be freely available to the public. The EPA should open up its decision-making process to congressional and public scrutiny to help reveal misuses of science Reforming the Regulatory Process: The White House should not change scientific findings in order to weaken, delay, or prevent new public protections. Ensuring Robust Scientific Input to EPA's Decision Making: The EPA should review and strengthen how it uses the scientific expertise of its staff and external advisory committees to create policies—especially when scientific input is critical or required by law. Depoliticizing Funding, Monitoring, and Enforcement: Problems with funding, monitoring and enforcement also need to be addressed by Congress and the next President to ensure that the EPA is the robust environmental agency that our country needs. Political interference is not unique to the EPA. Use the links on this page to explore surveys of scientists at other federal agencies and scores of examples of the abuse of science on issues ranging from prescription drugs to endangered species.

Executive Summary
snip...
The Bush administration’s direct abuse of science—combined with systemic changes to the regulatory system that threaten the in- tegrity of EPA science—highlight the need for strong action by the next president and Con- gress to restore scientific integrity to the agen- cy’s decision making. Only then can the EPA fully mobilize to serve the public good and ensure the nation’s health.

http://www.epa.gov/oppad001/records_of_decision_on_prions.pdf
CHAMBER OF COMMERCE OF THE UNITED STATES OF AMERICA WILLIAM L. KOVACS 1615 H S TREET , N.W. VICE PRESIDENT WASHINGTON , D.C. 20062 ENVIRONMENT , TECHNOLOGY & (202) 463 5457 REGULATORY AFFAIRS December 22, 2005
Likewise, some agency records of decision, as well as internal memoranda, establish precedent for regulatory policy making that at times extend the regulatory reach of federal agencies far beyond the statutorily mandated powers given by Congress. A recent example of a record of decision with regulatory impact would be the EPA’s decision to regulate prions.4 Prions are protein structures which, when infectious, are suspected of causing transmissible spongiform encephalopathy diseases, such as mad cow disease in cattle.5 EPA’s decision to classify prions as “pests” under FIFRA stems from an internal agency memorandum asserting jurisdiction over prions,6 even though prions are not living things (a prerequisite for EPA jurisdiction under FIFRA).7 Moreover, acting under the authority granted to itself in this memorandum, EPA issued emergency exemptions to several states to authorize the use of pesticides not registered under FIFRA to treat prioninfected surfaces. Therefore, EPA is treating this memorandum as though it is the issuance of a rule, without providing notice to the public or the opportunity to comment on the agency’s interpretation of its authoritative scope.8 The U.S. Chamber specifically requested EPA publish its prior discussion in the Federal Register for notice and comment, but EPA did not respond to that request. 3 Letter from Robert P.

Rulemaking to Establish Criteria for the Importation of Designated Ruminants and Ruminant Products From Canada into the United States Final Environmental Assessment, December 2004
While FSIS recommends the use of disinfectants, EPA regulates disinfectants under FIFRA. Prior to 2003, prions were not considered pests, and therefore their treatment with disinfectants was not regulated. In September of 2003, EPA classified prions as a pest (Hazen, 2004) and, therefore, the agency was required to regulate the “microorganisms” under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

White House invokes executive privilege in EPA inquiry
The Bush administration refuses to turn over subpoenaed documents related to the agency's decision to prevent California from enacting stricter emissions standards than the federal government.
By Richard Simon, Los Angeles Times Staff Writer
June 21, 2008
WASHINGTON -- Escalating a fight with Democrats on Capitol Hill, the White House on Friday invoked executive privilege in refusing to turn over documents to a congressional committee investigating the Environmental Protection Agency's decision to deny California permission to implement its own vehicle emission standards.
The Bush administration asserted executive privilege hours before the House Oversight and Government Reform Committee was to vote on whether to bring contempt-of-Congress proceedings against EPA Administrator Stephen L. Johnson and Susan Dudley, administrator of regulatory affairs in the White House Office of Management and Budget, for refusing to turn over subpoenaed documents.
Committee Chairman Henry A. Waxman (D-Beverly Hills) put off a vote on the contempt resolutions while he considers his options.
"I don't think we've had a situation like this since Richard Nixon was president," he said, appearing determined to press ahead, even if it leads to a court fight. "We don't know whether this privilege that's being asserted is valid or not."
Presidents since George Washington have claimed rights to executive branch confidentiality, according to the nonpartisan Congressional Research Service. The Bush White House invoked executive privilege to prevent officials from testifying about the dismissal of nine U.S. attorneys in 2006. President Clinton cited presidential privilege during investigations into the Monica Lewinsky scandal and on other issues.
House and Senate committees have been investigating what role the White House played in EPA decisions preventing California and other states from enacting tougher emissions rules than the federal government and in the EPA's approval of new ozone pollution standards.
The administration's claim of executive privilege is the latest twist in the escalating legal and political battle over California's efforts to implement its own law combating global warming. Critics of the EPA decision contend that it was based on politics, not science or the law.
As Waxman considered his next move in his fight with the White House, another House committee in the room next door grilled former Bush Press Secretary Scott McClellan, who wrote a revealing book about his days in the White House. The hearings were a sign of determination by Democrats not to ease up on their oversight activities, even in the final months of the Bush administration.
In asserting executive privilege in the EPA inquiry, the administration made public a copy of a letter sent to the president by Atty. Gen. Michael B. Mukasey saying that releasing internal documents "could inhibit the candor of future deliberations among the president's staff."
EPA spokesman Tim Lyons said the agency had provided the committee with more than 7,000 documents and devoted 2,200 hours of staff time to responding to requests for information, and he called it "disappointing" that the committee had decided to "politicize environmental regulations."
Jim Nussle, director of the Office of Management and Budget, took issue with Waxman's "sudden and unwarranted" move to consider contempt proceedings, noting that Dudley had appeared before Waxman's committee last month and was asked "only four questions" -- and only one by the panel chairman.
"There is no valid reason for moving from mutual cooperation to unilateral confrontation," Nussle wrote Waxman.
Waxman said: "I am very disappointed and disturbed that the administration is keeping this information from us, and I think we have a right to it."

what's the difference $$$
